The Persona (Toltz)

People are always saying that a person's character is unchangeable, but mostly it's the persona that doesn't change, not the person, and underneath that changeless mask exists a creature who's evolving like crazy, mutating out of control. I tell you, the most consistent person you know is more than likely a complete stranger to you, blossoming and sprouting all sorts of wings and branches and third eyes. You could sit beside that person in an office cubicle for ten years and not see the growth spurts going on right under your nose.
